Hello :-) You can take a look at youtube too. There are many TOEFL videos which explain all you need in order to do a good job. They explain the IDs you need to give them as well as all the phases required to get the TOEFL exams. Take care

As far as I know, the toefl exam is mostly on knowledge of written and spoken American English. You should read A LOT about all topics, as well as listen to people discuss them. One excellent website -or maybe it's more like a search engine-is www.about.com, you can enter VIDEO LIBRARY and choose among a variety of subjects, watch videos and find the trancript just below. I use it all the time as homework for my English students.

You should also look into books on class room management. TOEFL isn't only about grammar but how to teach it. This involves more than just the mechanics of teaching, but the politics and psychology of a classroom.

马里：我已经说英文。 我对toefl 考试陌生。我应该整天说英文。我觉得你的英文不错。
